To all whom t may concern.'

Be it known that I, OSCAR C. RIXsoN, a citizen of the United States, residing at New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Holders for Swinging Closures, of which the following is a full, clear, and exact description.

This invention relates to holders for swinging closures, such as transoms, hinged windows, and the like. More particularly, the invention relates to holders consisting of a tubular member having a second member slidably mounted therein, which members are pivotally secured to the swinging closure and its frame. The free movement of the two members is retarded to a more or less extent to vary the resistance which the swinging closure offers to being moved from one position to another.

One of the objects of the invention is to provide a holder of this character in which the device for retarding the free movement of the members is concealed within the tubular member and is provided with an adjustment which, while concealed from view, is nevertheless accessible after the holder has been assembled.

With these and other objects in View, the

invention contemplates a tubular member having a second member freely slidable therein, together with a device secured to one of these members, which is adapted to frictionally engage the other member and re-' tard its free sliding movement.

This device is concealed within the tubular member or casing and is preferably carried by the sliding rod. In the preferred form of the invention, an adjustable friction shoe is mount'- Fig. 4 is an enlarged detail showing the friction device.

Figs. 5 and 6 are transverse sections upon the lines 5-5 and 6-6 of Fig. 4; and

Fig. 7 is a transverse section through the screw cap closing one end of the holder.

The holder may be used with any type of swinging closure, and in the drawings the frame of such a closure is partially shown and indicated 1, a swinging closure 2, which is also only partially shown, being hinged to the frame, as at 3.

The holder shown comprises a tubular member 4, consisting of a tube formed of brass or other suitable material permanently closed at one end, as at 5. The other end of the holder is closed by a screw cap 6 provided with a slot 7 therein, through which projects a flat rod 8 which is freely slidable within the casing or tubular member 4. r1`he outer ends of this flat rod and the tubular member 4 are adapted to be pivotally secured to the swinging closure and its frame by any approved means. In the embodiment shown, a pin 9 passes through the outer end of the tubular member 4, and is pivotally secured to a bracket or support 10, which has a raised or offset middle portion which receives the head of the pin. The bracket is provided with openings 1Q, through which screws or other fastening devices 13 pass to secure the same rigidly to the frame 1 of the swinging closure. The outer end of the rod 8 is pivotally secured to an anchor piece 14, which anchor piece is pr`o'- vided with two upstanding ears or lugs 15, between which theend of the rod fits, the ears and rod being pivotally secured together by means of a pivot pin or rivet 16. The anchor piece 14 is rigidly secured to the rear face of the swinging closure by screws 17 or other suitable fastening means.

In so far as the construction has already been described, the rod 8 slides freely within the casing and theV parts would therefore oder no resistance to retard the free movement of the swinging closure. To accomplish this a friction device is provided, which retards the relative sliding movement of the rod and the tubular member. In the embodiment shown, this friction device comprises two shoes 20 and 21, which shoes7 as will be clear from Fig. 4, are arc shaped and of a curvature corresponding to the curvature of the inner wall of the tubular casing. The friction shoes are each provided with lugs 22 and 23, which lugs ft into slots 25 in the flat rod 8, and constrains these parts to move together. Interp'o'sed between one` which is preferably of resilient metal. set screw 2'? threaded into4 the flat rod, bears against this strip. An opening`28 formed in the shoe 21 is provided' for the head of the set screw. By turning the screw 27, the strip 26 may be puz'sliedl outwardly to forcethe shoe 20 into frictional .engagernenti wi'tl'i-l the i'nnerwall' of the tubular member. Tl-lie shoe 2l will also be forced into'engagem'ent with theV other portion of the ,inner wall."`

since the; edge of this shoe' rests against the fiat* rod, as willb'e clear from Fig;A 52 T-l'ie screw 2T lthereforev affords means for'- adjusting' thefri'ctional engagement between the shoes 20 and 2l andthe tubufar-member,

which may be regulated to a-rry'desiredI def-` gree so that the desired resistancei is provided to retard the free sliding i'n'ov'e'mentI of the rod 8 and the tubular member, whichl will, turn retard the free movement of the swinging closure.

.1f desired,v `the stripl 26 be of resilient material andmay be slightly bowed before4V the parts' are assembled, so that when the screw `27fis adjusted te 'straigh'ter'ly it, 'as

shown in the] drawings, al tension will be'` exerted* by the strip 26 in a' direction to' maintain the shoeQ'O in frictionalengagement with the inner 'wall of the tubular member. y y

To adjust the set screw 27 whenthe holder has been assembled, an opening 80' is pro-4vv` desired yto vary the resistance required" to* move the swinging` closure the same'may accomplished in an entirely simple manner; The screw capf 6 is preferably'provided' with a pin' or screw 31,- whi'ch' is'drivenlfor-v screwed into' aslot 32 in the' threaded end of the/'tubular member -k after the parts have- Copies of this patentfm'ay be yobtained-for frye centseach;` by addressing the-Commissioner of-Ptents, i

been assembled. This construction permits a relatively small angular movement of the screw cap which may be' required, due to the irregularity of movement of the rod 8, but will prevent the inadvertent unscrewing of the cap' 6. of these shoes and the flat rod is astrip 26,

I claim: v

1.A holder for swinging closures, comprising a tubular member, a rod freely slidable in said tubular member, means' for pivotally securingsaid-tubular member and rod to a swinging closure and its frame, a pair of segmental shaped friction slices carried by saidl rod and concealed within said tubular yfmember, and means for adjusting said shoes to vary the' friction between them and the inner wally of said tubular member.l

2. A holder for swingingv closures, comliiisiiiga tubular member, a flat rod freely slidablie'" iiil said-tubular member, means for pivotally'securmg said tubular member andl -rod ta swingingclosure-and' its frame', arc' otally securing sa-i'd tubularmem'b'er and rod I to a swinging closure and its frame', a fric'- tion shoe carried 'by said rod concealed with'- in said casing, air-adjusting screw carried by s'aiidlv rod, and a pi'ece'interposed between said 'shoes and" sai'dl adjustingy screw.

4; A holder for swinging4 closures, comprising tubular member, tele'scopiiigY rod' in said member, means for pivotalflfysecuring: saidtubular member and rod toa swinging closure and its frame, pair' of vfriction shoes carried: by said rod; an adjusting screw adapted to alter the fri'ctionalcontact -of said shoes and being .arranged'trans-Y verselyof the tubular ymember-and wholly within the same, said-tubular Vmember having'an' aperture inrits side affording'accessv `to saidscrew.
